Ultraviolet ray instrument



@et 3, 1936. c. w. sYMoNDs ULTRAVIOLET RAY INSTRUMENT Filed Oct. 13, 1934 I N VENTOR. @mam Patented Oft. la,` 1936 STATES 'PATENT OFFICE 3 Claims.

My invention relates to ultra-violet ray instruments of the type adapted to be inserted into a cavity of the human body for the purpose of sub- Jecting such cavity to the treatment of ultra-violet rays, and is a. further improvement upon the instrument shown in my United States Patent No. 1,794,557, in which I have shown various types of quartz rods for use with ultra-violet lamps, and which instrument is adapted to be inserted into cavities of the body.

' Among the salient objects of the present invention are: to provide an improved instrument with which a more universal discharge of such ultraviolet rays may be obtained to provide an instrui'nentdesignedy and constructed so that. it will converge a large number of ultra-violet rays and direct them to and through quartz elements which are so positioned that the rays will be directed outwardly through said elements radially out- ,20 Wardiy in all directions and` to all parts of the cavity into which the instrument may be inserted; to provide in an instrument of the character referred to a more practical construction and arrangement and one which will be more economically manufactured and which will, therefore, be more commercially successful for the purposes for which it is invented.

in the present invention, I have provided an instrument in which there is an inner member and an outer member, with annular space therebetween and in which the quartz elements are disposed so that the rays are directed first longitudinally through the instrument toward the end 'thereof' and thence outwardly ln all directions through the quartzelements interposed in the annular space between the inner and outer members.

In order that others may better understand my inventioml1 have illustrated the same on the accompanying sheet of drawing, which Iwill now describe.

Figure 1 is a. longitudinal sectional view through an instrument embodying myinvention; u

Figure 2 is a similar view of a slightly modied form of my invention;` and Figure 3 is a longitudinal sectional view through another form or embodiment of my invention, only the end portion of said instrument being shownf Referring now in detail tothe drawing, in. Fig. 1. I have shown a quartz lens l0, of a design to cover the aperature of the source of the ultraviolet rays, not shown, but which may be of any desired type, said lens being designed to converge the ultra-violet rays within a conical shaped mem- 55l ber il, merging in a tubular member I2, in which CII (Cl. 12S- 398) is a. quartz rod or bar i3, having a concaved receiving end I3 for receiving and directing the rays through the rod or bar to the end piece it, inserted into the end oi said tubular member l2, and including an outer cylindrical quartz meiri- 5 ber Ill' and an inner, conical quartz member ld, with small quartz elements l5, of irregular shape filling the space therebetween and adapted to direct or reiiect the ultra-violet rays laterally or outwardly from saidend piece. Said conical meml0 ber il may be provided with an access oriilling opening with closure therefor, designated il', for the purpose of supplying said conical member with any suitable liquid or :duid which will form a good conductor for ultra-violet rays. This l5 be distilled .water or other suitable iiuid.

In Fig. 2,1 have shown a similar structure lin-7 cluding a, quartz lens It, a similar conical member il, with closure member Il', and tubular portion i8, and end piece i9. At the juncture o' the 20 conical member il and the tubular member it, is a double concaved lens of quartz, or other suitable transmitting material, said lens being designated. 20. The end piece in this form of the invention is made of a uniforml cylindrical outer member 25 la', and a smaller uniform inner member l Q, with quartz balls 2l interposed in the annular space formed therebetween for directing or defiecting the rays outwardly in all directions therefrom.

In Fig. 3, I have shown a still further embodiment of my invention in which I use an outer quartz member 22 and inner quartz member it, with a spiral quartz rod interposed-therebetween and designated 2d, said end piece being inserted in a tubular member 25, similar to that portion of the construction shown in Figs. 1 and 2.' It will be understood, of course, that inasmuch as the spiral rod is a unitary member, the inner member 23 caribe omitted if desired for any reason. o

While I have shown and described three forms or embodiments of my invention in the way ci end pieces or portions, they are all for the purpose of receiving and directing outwardly in all directions as many ultra-violet rays as possible. The reason I have shown' the conical members il and il, and a large quartz lens for each, is to show means for gathering in a largernumber of the ultra-violet rays and directing them to the;V

fend piece, no matter what type of end piece may'ms y -be used, in order that the largest numberof ultraviolet rays possible may be directed into the cavityto be treated.

.I do not limit my invention to the details o! construction and arrangement shown for explan 55 atorypurposesnealizingthatmanychangescan be made therein without departing from the spirit of the invention, except as I may be lim- 'ited by the hereto appended claims.

I claim: 4 v 1. In a therapeutic instrument, means lfor deecting light rays which includes an outer eloninto` said instrument, an elongated end piecegaseoso forming a part of said instrument and including a tubular outer member or, quartz, an inner member of quartz extending lengthwise therein and of less diameter, and aquartz illler interposed between said inner member and said outer member and adapted to receive light rays from within said instrument and deilect them outwardly radially `vtherefrom.

3. In an instrument of the character referred to, an end piece consisting of a tubular quartz member adapted to be inserted into a cavity, and a quartz light ray deilecting element within' said tubular member to receive light rays from within said instrument and deect them outwardly. said quartz light ray deilecting element being in the cLEoN w.fsYMoNDs.
